has developed passively Q-switched continuously pumped Nd:YVO4 generating
~16 ns wide pulses at ~70 kHz repetition rate by end pumping an Nd:YVO4
crystal of 1 mm thickness and 3 mm x 3 mm cross-section employing a CW laser
diode with maximum output power of 700 mW at 808 nm.
Experiments are in progress to generate second harmonic and to further reduce the pulse widths that will lead to several scientific and defence applications.
